Polymorphism of the 86th amino acid in CX26 protein and hereditary deafness

引用

Journal of Otology 2016年第2期11卷 84-87页

作者： Xi Shi Shiwei Qiu Fendong Yan Lizhang Shi Yili Xuan Wei Zhuang Yingli Bei Hanli Yao na yuan Mingyang Shi Yuehua Qiao Institute of Audiology and Balance Science Xuzhou Medical University Department of OtolaryngologydHead & Neck Surgery Institute of Otolaryngology of PLA Chinese PLA General Hospital Clinical Hearing Center Affiliated Hospital of Xuzhou Medical University

Objective:To investigate the membrane localization function of the CX26 protein when its 86th amino acid is Thr, Ser or Arg, and its relations to deafness. Methods:CX26-GFP protein with either Thr, Ser or Arg as the 86th amino acid was expressed in mouse SGN cells via the GFP fusion type lenti-virus expression system. The membrane localization of the fusion protein was observed under a fluorescence microscope. Results:The mutated protein of CX26 T86S was localized to cell membrane and form gap conjunction structures, showing no difference to the wild type CX26 protein (with Thr as the 86th amino acid). However, the gap conjunction structure disappeared when the mutation was CX26 T86A. Conclusion:These results indicate that the CX26 T86R mutation may be a cause of hearing loss, but CX26 T86S as a non-pathogenic poly-morphism mutation does not affect functions of the CX26 protein. The results are in accordance with the results of clinical screening.

在通信系统中,信道估计的准确与否直接影响到接收端符号的检测性能,对MIMO系统更是如此。本文首先介绍隐含序列的信道估计方法,并分析此类方法存在的问题,包括信道估计性能受发送端符号数据的影响以及受未知直流偏移影响。然后,重点研究基于ZCZ(Zero Correlation Zone)训练序列的DDST(Data-De-pendent Superimposed Training)方案,此方案可以实现多天线系统的多径信道和直流偏移联合估计。最后,给出理论分析和仿真结果,二者均表明平衡ZCZ训练序列不但能分离直流偏移估计和信道估计,而且能使二者的估计均方差性能同时达到最优。

In vivo Inhibition of naS Preparation on H9N2 Subtype AIV

Virologica Sinica 2010年第2期25卷 145-150页

作者： Ruo-feng SHANG Jian-ping LIANG Zhong-yuan na Hong-jun YANG YU LU Lan-ying HUA Wen-zhu GUO Ying CUI Ling WANG Key Laboratory of New Animal Medicine Project Chinese Academy of Agricultural Sciences Lanzhou Insititute of Animal Husbandry ＆ Veterinary Pharamaceutics Science Chinese Academy of Agricultural Sciences Lanzhou 730050 China Yunnan Eco-agricultural Research Institute Kunming 650106 China

naS preparation, a kind of Chinese herbal medicine found by the Yunnan Eco-agricultural Research Institute, has potential antiviral activity. In this paper, the inhibiting effect of naS preparation on H9N2 subtype Avian influenza virus (AIV) was investigated in vivo. Chickens infected with H9N2 virus were treated with naS preparation for 4 days. The virus was then detected by hemoagglutination (HA) test and reverse transcription polymerase chain reaction (RT-PCR). The results showed that no H9N2 virus could be detected at the 7th day when the chickens were treated with 0.2g/kg/d or 0.1g/kg/d of naS preparation. However the virus could be detected in other chickens without naS preparation treatment. This result suggested that naS preparation may be a potential drug candidate to control infection of H9N2 subtype AIV in chickens.
